Hi Jim,
From what you've described, I think you need to use the modulated IRIG output.
I sent a previous email to that effect.
The audio card IRIG drivers expect IRIG B data
used to modulate an audio carrier (AM).

My clock generates a couple variants of IRIG-B. I wasn't able to find
docs on what variant of IRIG-B that NTP expects. I know one variant
(which I tested, but am not using, nor do I expect to work) is high
precision, and is supposed to include the same accuracy as standard
IRIG-B + 1kPPS.

This may sound a bit basic, so apologies if you have already passed this
particular hurdle, but there are several different types of IRIG time code.
A number of the clocks I have which generate IRIG can generate different
versions of IRIG (e.g. IRIG B, IRIG H)
If memory serves, the NTP code expects IRIG B.
Have you confirmed that's what your clock is currently configured to
generate?
